#749: Dark Energy Changing Over Time
We thought Dark Energy was constant, but new results from DESI say maybe not, and if it wasn’t the Hubble Tension would be easier to solve.
#748: Fast Radio Bursts
Fast Radio Bursts the briefest of moments, some dead stars can flash brighter than their entire galaxy (in Radio light) and then live to do it again and again. It’s time for an update on fast radio bursts, a phenomenon we’ve only known about for a few decades.
#747: Rogue Planets
Most planets orbit stars. That’s the rule, right? Sometimes planets just go rogue. Let’s learn about planets living free from stars.
#746: Dust Storms
What causes these storms and how do they work differently on the worlds in the solar system. But what about the exoplanets?
#745: How We Know if Asteroids Will Attack
New asteroids are found every day, and every day we learn that those asteroids don’t have any murderous intentions. But how do we learn that?
#744: Lunar Time
What time is it on the Moon? The Moon orbits the Earth, so it doesn’t fall into a specific time zone. It’s time to introduce Lunar Time.
#743: What Else Can We Learn From Gravitational Waves?
Sure, the masses of merging black holes are nice to know, but what else can we learn from gravitational black holes?
#742: Atmospheric Gravity Waves
Gravity Waves … not gravitational waves … move atmospheres and make pretty clouds.
#741: Technosignatures
Pollution will ultimately give away a society.
#740: Sneaky Stars
If you’re an astronomer you depend on accurate observations of stars, but there’s a problem. Stars are sneaky! Changing in size, brightness, color, they hide their chemistry, their age and even their companions from all but the cleverest observers. Stars explode...
